For the electronic products commonly found in the current technology market, there are generally two types of 5V1A phone chargers and 5V2A phone chargers. Here, we introduce the application scope and difference of the two chargers.

 

First of all, we should pay attention to the scope of its application. 5V1A chargers are commonly found in small electronic devices such as our smartphones and MP3s, MP4s, and tablets smaller than 7 inches, mainly because of their smaller electronic components and screens, and lower power consumption. However, 5V2A is generally used for large-scale electronic devices, such as tablet computers, and now many 5V2A chargers are used in tablet PCs.

General electronic products will mark their own charging level. If the 5V1A device uses a 5V2A charger, it will not affect its use, but the life of the device will have a certain impact. On the contrary, the 5V2A device uses a 5V1A charger, which can easily damage the charger. In fact, whether it is 1A or 2A, it is only the difference in current quantity. The higher the current, the faster the charging speed. Many small electronic devices such as mobile phones do not have too many restrictions. We should pay attention to this problem when using it to avoid damage to electronic components.

 

For its service life and charge, 1A is generally less than 2A, but many manufacturers now increase the resistance and capacitance when making the charger, so it will not affect the actual use. Since 1A and 2A will be different in power, the general 1A can provide 5W and the 2A provides 10W. In this aspect, you should pay attention to the requirements of its electronic products. Select the appropriate power and remember not to overpower. Operation, can not be used often for power failure. For today’s electronics manufacturers, they are also expanding the range of charging that their products can be used. This also facilitates conditions such as fast charging and also promotes the development of chargers.
